| Abstract: | Objective]To optimize the supercritical extraction conditions of essential oil from tobacco and analyze the chemical compositions,so as to provide means for the analysis of constituents of tobacco aroma and development of tobacco essence.Method]Each influencing factor was optimized and the chemical constituents were analyzed with GC-MS.Result]The optimal extraction conditions were optimized to be as follows:sample of tobacco powder,extraction pressure of 300 bar,temperature of 40 ℃,entrainer of absolute ethanol and the added amount of 0.10 ml/min,static extraction duration of 30 min(with 3 ml absolute ethanol in) and dynamic extraction duration of 1.5 h.In addition,the major chemical constituents were nicotine(58.040%),Neophytadiene(14.679%) and vitamin E(9.848%) etc..Conclusion]The optimal extraction conditions were obtained in this study,which provides the new means for the the analysis of constituents of tobacco aroma and development of tobacco essence. |
